The mansion was built by the same eccentric architect responsible for the Quinta da Regaleira in Sintra.
The site was historically a hermitage, established after a reported Marian apparition in the 15th century.
The location serves as a primary geographic vantage point for spotting migratory birds in the region.
Archaeological findings suggest the hilltop was a site of human activity long before the construction of Christian structures.
The interior of the palace has been largely inaccessible to the general public for decades to prevent structural damage.
Due to the high elevation and exposed cliffside position, local weather conditions often differ drastically from the beach levels below.
The Sanctuary of Peninha occupies a 488-meter-high granite outcrop within the Sintra-Cascais Natural Park, overlooking the Atlantic coastline. The site features a 17th-century chapel dedicated to Our Lady of Peninha and an adjoining Revivalist mansion commissioned by António Augusto Carvalho Monteiro in 1918. The mansion blends Neo-Manueline and Gothic architectural elements, though it remains largely unfinished and currently serves as a restricted-access historical landmark. Visitors can walk around the exterior grounds, which offer 360-degree views of the Guincho beach, Cabo da Roca, and the Sintra Mountains. The location is known for its intense wind exposure and frequent maritime fog. The chapel itself contains 18th-century tile panels and a wooden altar. The site sits at the end of a rocky ridge, serving as a historic pilgrimage point that predates the construction of the palace.

Bring a sturdy windbreaker, as the hilltop is subject to strong, persistent gusts.
Wear hiking-appropriate footwear to navigate the uneven, rocky terrain surrounding the structures.
Check local fog forecasts, as visibility can drop to zero within minutes, obscuring the coastal views.
Do not attempt to enter the fenced-off or boarded-up sections of the mansion, as the structure is unstable.
The mansion interior is permanently closed to the public; the grounds are open year-round, weather permitting.
Maintain silence near the chapel, as it remains a site of religious significance; keep to marked paths to protect the fragile cliffside vegetation.
